A number of months back, I grabbed three PCs off the curb: an IBM server, a Toshiba desktop replacement laptop and a custom-built PC with a dead power supply and motherboard that was probably bad too. I stripped that machine for parts; I got a non-functional 160GB SATA hard disk, an NVIDIA graphics card, a reader for various SD cards and I got the 3.2GHz Pentium 4 640 microprocessor out of it.
My HP Compaq dc7600, which has since become a secondary machine, initially had a 3.0GHz Pentium 4 630. The Pentium 4 630 and 640 are both Hyperthreaded CPUs, and the 640 is only 200MHz faster than the 630 (3.2GHz as opposed to 3.0GHz), so it's not much in the way of an "upgrade", but I installed it in the machine regardless.
I have not updated the system's benchmark tests since I upgraded the processor. Both benchmark scores were achieved using Geekbench 2 Tryout (so tests were limited to 32-bit, but that's okay since I don't have 64-bit Windows installed even though this processor is capable of 64-bit computing), so here are the results, before and after:
Pentium 4 630, 3.0GHz w/Hyperthreading

Total Score: 1883
Integer Performance: 1937
Floating Point Performance: 1835
Memory Performance: 1821
Stream Performance: 1989
The benchmarking improvements are apparent, although not very significant. I have not noticed any real-world improvements; games don't perform much faster with the exception of The Sims 2 and The Sims 2 Castaway Stories, which saw a small increase in framerate. The biggest benchmark improvements were the integer performance and the floating point performance, where scores rose 116 points and 104 points respectively, while the memory performance increased a little bit and the stream performance decreased a little bit.
